Special white high-performance cement-based material for external wall facing brick reverse beating process

Abstract

The invention discloses a special white high-performance cement-based material for an external wall facing brick reverse beating process. The white high-performance cement-based material is characterized by comprising white cement, white quartz sand, mineral powder, titanium dioxide, an additive and water. The white high-performance cement-based material comprises, by volume, 785-933 Kg / m<3> of the white cement, 976-1095 Kg / m<3> of the white quartz sand, 130-215 Kg / m<3> of the mineral powder, and 207-246 Kg / m<3>; and the titanium dioxide accounts for 1-3% of the mass of the white cement, and the additive accounts for 0.29-0.38% of the mass of the white cement. The white high-performance cement-based material has the characteristics of strong flowability, good anti-drawing performance and good decoration performance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a white high-performance cement-based material specially used for the anti-beating process of exterior wall bricks. Background technique [0002] In the process of counter-beating the exterior wall bricks, a white cement base material is needed to play the role of adhering the exterior wall bricks and jointing the exterior wall bricks; the existing white jointing materials are not fluid enough, so jointing treatment is required It is time-consuming and labor-intensive, and the pointing effect depends on the technical level of the workers, and the apparent effect is not good enough; and the existing materials have poor pull-out resistance, which cannot meet the process of back-beating exterior wall bricks. At the same time, ordinary concrete materials are prone to shrinkage and cracking, which not only affects appearance but also reduces durability. [0003] In view of the above...
